We have studied composition of the bulk and surface of the nanocrystalline Fe72.5Nb4.5Cu1Si10B12 alloy prepared from the amorphous one in dependence on gaseous environment during the crystallization annealing. It was found that the mixture of Ar+H2 causes differences in the phase composition between bulk and surface layer that influences magnetic properties of the whole sample.
